Average is defined as a value found by adding all of the numbers in a set together and then dividing them by the quantity of numbers in the set. Six is an example of the average of five and seven.

2. Boat and stream

If a boat or a swimmer moves in the opposite direction of the stream, then it is called upstream. Downstream: If a boar or a swimmer moves in the same direction of the stream, then it is called downstream. When the speed of a boat or a swimmer is given, it usually means speed in still water.

3. Compound interest

Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously accumulated interest.

4. MIXTURE & RATIO

a ratio is a relationship between two numbers indicating how many times the first number contains the second. ... When two quantities are measured with the same unit, as is often the case, their ratio is a dimensionless number.

5. Partnership

Partnership is an important chapter in Quantitative section of IBPS and other banking examination.
When two or more people joins hands with a common goal to attain profits. Every partner invests either time, money or his patents to help partnership firm to reap profits.
There are many problems in partnerships regarding profit shares, investment period etc. I will try to solve one question from each part.

6. Percentage

A percent is a ratio whose second term is 100. Percent means parts per hundred. The word comes from the Latin phrase per centum, which means per hundred. In mathematics, we use the symbol % for percent.

7. PIPES & TANK

Quantitative aptitude questions on pipes and cisterns are similar to time and work problems. They are commonly asked questions for bank tests, career recruitment tests, management entrance tests and other competitive exams. Questions on pipes and cisterns can be mixed with questions on mixtures and alligations to increase the difficulty level of questions. Quantitative aptitude questions on pipes and cisterns when mixed with ratios can be a bit tricky. But a strong understanding of the concept behind solving them and practicing as much questions as possible can help you easily solve them.

8. Profit And Loss

Now if you compare, a profit of Rs.10 on an article of Rs.10 is way better than a profit of Rs.100 and Rs.4000. Therefore profit and loss is calculated in percentage and for this, we always consider CP as 100% and SP as 100% plus profit% or 100% minus loss%.

9. Ratio and Proportion

This is called a rate and is a type of ratio. A ratio is a way to compare two quantities by using division as in miles per hour where we compare miles and hours. A proportion on the other hand is an equation that says that two ratios are equivalent.

10. Simple Interest

Use the formula i = prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.

11. Time & Distance

An easy way to remember the distance, speed and time equations is to put the letters into a triangle. The triangles will help you remember these 3 rules: Distance = Speed x Time.

12. Time & Work

Time and Work Definition. Work is something that is done, for example, pushing a table, making projects etc. Work may be considered as a job. The time taken to complete a given work depends on only one factor that is the number of persons employed to do the work.

A 2D geometric model is a geometric model of an object as a two-dimensional figure, usually on the Euclidean or Cartesian plane. Even though all material objects are three-dimensional, a 2D geometric model is often adequate for certain flat objects, such as paper cut-outs and machine parts made of sheet metal.

3D GEOMETRY

The topic of three dimensional geometry is quite important and a bit complicated as compared to its counterpart two dimensional geometry. One of the ways of describing a 3D object is by approximating or assuming its shape as a mesh of triangles.

COORDINATE GEOMETRY

Definition of Coordinate Geometry. ... A coordinate graph is a rectangular grid with two number lines called axes. The x-axis is the horizontal number line and the y-axis is the vertical number line. The axes intersect at the origin which is the point (0,0).

GEOMETRY

Geometry (from the Ancient Greek: γεωμετρία; geo- "earth", -metron "measurement") is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the field of geometry is called a geometer.

HCF - LCM

For example, LCM of 10, 15, and 20 is 60. Highest Common Factor (HCF): The largest or greatest factor common to any two or more given natural numbers is termed as HCF of given numbers. Also known as GCD (Greatest Common Divisor).For example, HCF of 4, 6 and 8 is

HIGHT & DISTANCE

The angle of elevation of the point on the object (above horizontal level) viewed by the observer is the angle which is formed by the line of sight with the horizontal level. ... To solve height and distance problems, trigonometric ratios for standard angles (table 1) should be remembered.

SIMPLE INTEREST

Simple interest is a type of interest that is applied to the amount borrowed or invested for the entire duration of the loan, without taking any other factors into account, such as past interest (paid or charged) or any other financial considerations.

TRIGONOMETRY

As you see, the word itself refers to three angles - a reference to triangles. Trigonometry is primarily a branch of mathematics that deals with triangles, mostly right triangles. In particular the ratios and relationships between the triangle's sides and angles.

STATICS

Trigonometry (from Greek trigōnon, "triangle" and metron, "measure") is a branch of mathematics that studies relationships involving lengths and angles of triangles. ... Trigonometry is most simply associated with planar right-angle triangles (each of which is a two-dimensional triangle with one angle equal to 90 degrees).
